Flexor and Extensor Muscles

Topic: Flexor and Extensor Muscles

Question: Which muscles are stronger, flexor or extensor muscles?

Hypothesis:I think my flexor muscle is stronger than my extensor.

Procedure:

1. Get into groups
2. Have one person stand up straight with his / her back against a wall.
3. Have that person hold the weights in his / her dominant hand
4. In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
5. Repeat steps 2-4 for each member of the group.
6. Record the data for each member of the group.
7. Have the first person stand as straight as possible near a wall.
8. Have the student hold the weights with his / her dominant arm bent near the ear.
9. In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
10. Repeat steps 7-9 for each member of the group.
11. Record the data for each member of the group.

Data:



Conclusion: My hypothesis was wrong. It was rong because as you can see my data the total for extensor was higher than the flexor total.
